Radiating preventing copper-clad aluminum wire

The invention relates to a radiating preventing copper-clad aluminum wire. The radiating preventing copper-clad aluminum wire is composed of a plurality of wire bodies. Each wire body is composed of a copper core, a pure aluminum layer and an aluminum oxide layer, wherein the pure aluminum layer is combined to the outer surface of the copper core through the metal combining technology, and a plurality of braided wires are stranded. Each wire body is externally provided with a tin coating, and wherein the combination is wrapped by the aluminum oxide layer. Each copper core comprises, by weight, 2.5%-3.0% of iron, 3% of phosphorus, 0.1%-0.6% of rare earth, 1%-3% of nickel, and the balance copper.
